Scope

Helping traffic get around an incident or event—The requirements define a system that will divert traffic and people around an incident scene or the location of an event. The details of this diversion are called an "incident response plan" but could also be called a “traffic/traveler management around an incident or event” plan.

Freeways, arterials, and mass transit operations—Rather than focusing on freeways alone, the requirements define a system that uses multiple roadways and modes in a coordinated way to get traffic/travelers around an incident or event.

Managing normal daily traffic—The requirements are not meant to define a system that will improve day-to-day traffic on an ongoing basis.

Managing the scene of an incident/event—While the system would divert traffic around an incident or event, it is not intended to manage what happens at the incident/event itself.  That remains under the control of emergency responders. For example, the proposed ICM system:

1. Does not expect first responders to change their processes or priorities at the actual incident scene or event location. It will request improved communication from first responders as part of the ICM process but will not alter responders' internal methods already in place for incident/event scene management.
2. Does not suggest road or lane closures. Safety officers on the scene determine which lanes to close and for how long. The ICM system only requires input on which lanes are closed, how long the closures will last, and when the lanes are to be reopened.
3. Does not explicitly suggest or enable routes for first responders to reach an incident or event location.
